CLIP FOR DETECTOR-BARS.

Specification of Letters Patent.

Patented June 26, 1906.

Application filed April 19, 1904. Serial No. 203,887.

T0 at whom it may concern:

Be it known that I, JAMEs T. I'IAMBAY, a citizen of the United States, and a resident of the city of New York, in the State 01 New York, have invented certain new and useful Improvements in Clips for Detector-Bars, of

which the following is a specification.

My invention relates to improvements in clips for detector-bars; and the object of the invention is to produce a clip which will be compact, easily operable, and which will require a minimum of attention in order to keep the same in proper condition for producing eflicient service.

Other ob 'ects and advantages will be hereinafter pointed out.

In the following I have described with reference to the accompanying drawings one form of device embodying my invention, the particular features thereof being hereinafter pointed out in the claims.

Similar letters of reference indicate similar parts throughout the several views.

In the drawings, Figure 1 is an elevation of a section of rail, showing the clip in place thereon and in connection with a detectorbar, parts being broken away. Fig. 2 is a transverse sectional view of the parts shown in Fig. 1 along line AB. Fig. 3 is a horizontal Few, partly in section, along line C D of It indicates the ordinary T-rail, to which the clip is adapted to be attached and along which the detector-bar b is to be operated. The bracket for supporting the various partsof the clip comprises a central portion a, conforming to the shape of the rail, as shown in Fig. 2, and arms (1 (1, each provided with a bracket e and a lugf for the purposes hereinafter described. The base of the central portion 0 fits over the base of the rail a, as shown in Fig. 2, and is provided with a hollow socket h, adapted to receive the pin i, preferably formed with rounded ends, as shown. The bracket is adapted to be clamped to the rail by bolt 9' passing through the web of the rail and the central portion 0, as shown. The link 7c is provided at its lower end with a hollow flanged socket 1, adapted to fit over the socket h and to inclose the pin i, on which it is pivoted. The upper end of the link 1c is provided with a hollow socket m, resting against the detector-bar b and adapted to pivotal movement on the pin a, riveted to the detector-bar. A loop 0 is formed on the rear of the link and is adapted to receive a strap 17, the ends of'which are bolted to the supporting-bracket by means of bolts 1" r in brackets e. Sockets Z and m are each provided with an oil-hole s and a hood t,projecting over the oil-hole, so as to keep dust and dirt from falling therein.

In the use of the-apparatus described the supporting-bracket is first clamped to the rail (1 by means of the'bolt j, the central portion 0 being wedged between the head and the flange of therail and the lugs f f abutting against the web in such manner as to keep the bracket in alinement with the rail and, in connection with the wedging against the head and base of the rail, form a solid and substantial support for the detector-bar and its operating parts. The supporting-bracket having been clamped to the rail, as described, the pin 'i is dropped loosely into the socket h, and the link is fitted on over the rivet n in the detector-bar b and the pin 'b 1n the socket h.

The strap p is then passed through the loop 0 and bolted to the brackets 6, thus firmly uniting all of the parts together. Oil may be provided for the rivet n and the loose pin 'L through oil-holes s s in the sockets m and 1, respectively, the socket It being adapted to form an oil-cup by being suitably inclined and closed at the bottom, the pini being permitted to freely rotate therein.

It is seen from the description and the drawings that the parts are firmly and com pactly held together without any unnecessary projections. The strap 19, link I: against the outward thrust of the detector-bar when the same is oscillated, is advantageously disposed at the rear of the link, where it is not so liable to be broken as if it was on the front of thelink. The lugs f f, as has been stated, keep the parts in alinement, so that any unevenness in the rail will not interfere with the proper application of the clip. The loose pivot or pin '5, freely rotatable in the sockets h and l, as described, after the parts have been adjusted and fastened together and oil has been supplied, needs no attention. The pin may also be formed with rounded ends, as illustrated, which give rise to little or no friction, articularly when working in the oil. T ere are no parts to wear unduly, and the clip, as shown and described, is of economical construction and of exceeding durability without the necessity of constant attention.

It is obvious that the details of construction may be varied without departing from holding the the spirit of my invention, and I do not restrict myself to the details shown.

Having described my invention, What I claim, and desire to secure by Letters Patent, 1s

1. In an apparatus of the character described a detector-bar, a bracket, a link pivoted on said bar and supported in said bracket, and means inside the link for holding the same against outward thrust.

2. In an apparatus of the character described a detector-bar, a bracket, a link pivoted on said bar and supported in said bracket, a loop on the inside of the link and a strap adapted to pass through said loop to hold the link against outward thrust.

3. In an apparatus of the character described, a detector-bar, a bracket, a pin resting loosely in the bracket and a link pivoted on the detector-bar and adapted to rest loosely over the pin in the bracket.

4. In an apparatus of the character described a detector-bar, a bracket, a socket in 5.. In an apparatus of the character described a detector-bar, a bracket, a socket in the bracket adapted to form an oil-cup, a pin resting loosely in said socket adapted to retate therein and a link pivoted on said pin.

6. In an apparatus of the character described a detector-bar, a bracket, a socket in the bracket closed at one end and adapted to form an oil-cup, a pin resting loosely in said socket adapted to rotate therein and a link loosely pivoted on said pin.

In Witness whereof I have hereunto signed my name in the scriblng Witnesses.
